Check Your Air Compressor Parts
The responsibility of owning an air compressor ปั๊มลม is often forgotten. It is not until the breakdown of one or more of the many compressor parts, causing all work to halt to a standstill, that the neglect of maintenance becomes apparent. Fortunately, an air compressor is in itself a very straightforward and robust machine, making this problem easy to solve.
Remember, before performing any maintenance on power operated equipment think SAFETY FIRST and read the instruction manual carefully
Air tanks
The air tank in the compressed air system should be drain regularly. As air is compressed, it loses its ability to hold moisture. This results in condensation of water, usually in the air tank, but sometimes in other parts of the system as well. As we know, water results in corrosion when mixed with air, so draining the air tank will increase the life span of the air reservoir. It will also improve the quality of the compressed air, which is so necessary for an airbrush compressor.Air filters
The air filter keeps foreign particles out of the compression chambers and compressed air system. It plays a significant role in the operating condition of your compressor and should be replaced as recommended by the instruction manual. The air filter is very easy to replace and often quite inexpensive to purchase as well. In technical plants where I have been an engineer, the air filter replacement interval has been at least once every year, regardless of its condition. I consider a fresh air filter to be a great asset for any compressed air system.Drive belts
Piston compressors often have drive belts made of rubber. As the belt gets older you will have to retighten the belt to ensure optimal grip, between the drive belt and the drive belt wheels. You can find out if there is to slack much on the drive belt, simply by pushing it up and down. If you can push it more than 2-3 centimetres in either direction, it needs retightening. To retighten the drive belt, just reposition one of the belt drive wheels with its adjustment screw. This will increase the distance between the belt drive wheels and thus tighten the drive belt. When the belt drive wheels are in their extreme position, or if the drive belt itself is damage in any way, the drive belt needs replacing. If your compressor makes a squeak every time it starts, this is particularly easy to notice on a quiet air compressor, have the look at the drive belt which probably needs retightening or replacing.Pressure Switches
The pressure switch is what controls the compressor. A worn or faulty pressure switch may increase the stop and start interval of the compressor motor, which can reduce the air compressors lifespan. The pressure switch is also responsible for keeping a correct air pressure in the system, ensuring optimal performance of your air compressor parts and tools. To check your compressors pressure switch, just remove the pressure switch cover and lower the pressure set-point with abutting 0,5 bar (7,5 psi). When the air compressor is started again, observe on a pressure gauge attached to the air tank, if the new pressure set-point is achieved. If it is, adjust the pressure switch back to its original setting and make a new observation of the air pressure after start up. If the pressure has now risen to the initial pressure set-point, the switch is working fine.When the pressure switch eventually does fail, refer to your air compressors instruction manual to find spare parts and how to change it.
Safety Valves
The safety valve is there to prevent the pressure from rising above the safe working pressure of the air compressor. The safety valve is usually just a simple spring loaded valve located on the air compressor exhaust line. The safety valve is calibrated for a particular pressure, matching your exact compressor. You can usually test the safety valve by pulling on a ring, or pushing a button on the valve. By doing so, you are operating the safety valve. There should be some resistance when doing this, but it should move freely. If the safety valve is stuck, leaking or you are suspicious of it not working properly, stop using the compressor immediately and consult the instruction manual.
Compressor Oil
The air compressor oil lubricates the air compressor. The compressor oil is also transported with the compressed air out to the other air compressor parts and tools and thereby acts as a lubricant for these components as well. Make sure to check the oil level on your compressor regularly and top it up if it’s low. The air compressor oil is subject to oxidation, heat and humidity, which all play a significant role in determining the lifespan of the compressor oil. Make sure you change the air compressor oil at intervals recommended by the instruction manual.read more http://www.clinton-marketing.co.th/AIR-COMPRESSOR
